Raws li qhov tam sim no yog tus nqi ntws ntawm raug them cov khoom hu ua electrons. Cov nqi ntsib lub zog xwb hauv hluav taws xob teb, whereasthe tam sim no ntsib ob lub zog hauv hluav taws xob thiab magnetic teb. Lub coulomb yog chav tsev ntawm hluav taws xob nqi , hos cov tam sim no yog ntsuas hauv amperes.
Ib yam li ib tug yuav nug, puas yog hluav taws xob tam sim no thiab hluav taws xob them tib yam?
Ib hluav taws xob tam sim no yog tus nqi ntws ntawm hluav taws xob dhau ib qho taw tes lossis cheeb tsam. Ib hluav taws xob hais tias muaj nyob thaum muaj net ntws hluav taws xob dhau ib cheeb tsam. Hauv hluav taws xob circuits qhov no nqi feem ntau yog nqa los ntawm electrons txav los ntawm ib lub xaim.
Ib tug kuj yuav nug, hom nqi dab tsi nyob rau hauv hluav taws xob tam sim no? Muaj ob hom ntawm hluav taws xob nqi , zoo thiab tsis zoo. Qhov zoo raug them teeb meem raug tshem tawm ntawm lwm qhov zoo raug them teeb meem. Txawm li cas los, lawv yog attracted rau negatively raug them teeb meem.
Kuj paub yog, qhov txawv ntawm qhov tam sim no thiab electrons yog dab tsi?
Qhov ntws ntawm electrons yog term hluav taws xob . Hluav taws xob ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Cov pa tam sim no los yog yooj yim tam sim no , coj tus cwj pwm zoo li cov cab kuj ua rau tam sim no flow. Conventional tam sim no ntws los ntawm qhov zoo terminal mus rau tom qab ntawd.
Tus qauv ntawm lub hwj chim yog dab tsi?
Ohm txoj cai sib npaug ( qauv ): V = I × R andthe zog txoj cai equation ( qauv ): P = I × V. P = zog , I lossis J = Latin: influare, thoob ntiaj teb ampere, orintensity thiab R = resistance. V = voltage, electric potentialdifference Δ V or E = electromotive force (emf = voltage).

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
Dab tsi yog qhov txawv ntawm qhov ratio ntawm qhov ratio thiab tus nqi?
Ib qho piv txwv piv qhov loj ntawm ob qhov ntau. Thaum qhov ntau muaj qhov sib txawv, ces qhov piv yog hu ua tus nqi. Ib qho piv txwv yog ib nqe lus hais txog kev sib npaug ntawm ob qho piv txwv
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
